Make a spicy version
If you want to dial up the heat, add a chopped serrano or jalapeño pepper with the onion, or use a spicier hot sauce than chipotle.
Make a healthier version
I'll often make mine using low-fat sour cream and mayonnaise. It doesn't suffer in the slightest!
Hot or cold?
In Mexico, esquites are mostly served hot, but I also like to serve mine at room temperature. You can prepare esquites up to 3 days in advance and keep refrigerated until you need. Then just leave to come to room temperature for an hour. I love them hot or cold, so you can decide which you like best.
Can I use canned or frozen corn?
Personally, I would say frozen is fine, but no to canned corn - It will make the esquites a little mushy. Fresh is by far the best, so count the days 'til the juiciest fresh corn is in season between May-Sep (US).
Try grilling the corn instead
Try grilling the corn on the bbq to char it lightly, then remove from the cob. It'll add a smoky flavour to the finished dish which is quite special! Simply stir the charred corn into the sauteed onion and stir in the remaining ingredients.
